`response_model` parametresinde `dataclasses` da kullanabilirsiniz:

{* ../../docs_src/dataclasses_/tutorial002_py310.py hl[1,6:12,18] *}

Dataclass otomatik olarak bir Pydantic dataclass'ına dönüştürülür.

Bu sayede şeması API docs kullanıcı arayüzünde görünür:

<img src="/img/tutorial/dataclasses/image01.png">

## İç İçe Veri Yapılarında Dataclass'lar { #dataclasses-in-nested-data-structures }

Örneğin alfabetik sıralamada `users`, `items`'tan sonra gelirdi; ancak listedeki ilk sözlük olarak `users` metadata'sını eklediğimiz için, dokümanlarda önce o görünür.

## OpenAPI URL'si { #openapi-url }

Varsayılan olarak OpenAPI şeması `/openapi.json` adresinden sunulur.

Ancak bunu `openapi_url` parametresiyle yapılandırabilirsiniz.

Örneğin `/api/v1/openapi.json` adresinden sunulacak şekilde ayarlamak için:

Örneğin:

{* ../../docs_src/behind_a_proxy/tutorial003_py310.py hl[4:7] *}

Şöyle bir OpenAPI şeması üretir:

```JSON hl_lines="5-7"
{
    "openapi": "3.1.0",
    // Burada daha fazla şey var
    "servers": [
        {
            "url": "/api/v1"
        },
        {
